Public Methods

Method Description
Clone ( ) : object

Creates a new object that is a copy of the current instance.

DistributionFunction ( double x ) : double

Gets the cumulative distribution function (cdf) for this distribution evaluated at point k.

The Cumulative Distribution Function (CDF) describes the cumulative probability that a given value or any value smaller than it will occur.

LogProbabilityDensityFunction ( double x ) : double

Gets the log-probability density function (pdf) for this distribution evaluated at point x.

The Probability Density Function (PDF) describes the probability that a given value u will occur.

MannWhitneyDistribution ( double ranks, [ n1, [ n2 ) : System

Constructs a Mann-Whitney's U-statistic distribution.

ProbabilityDensityFunction ( double x ) : double

Gets the probability density function (pdf) for this distribution evaluated at point u.

The Probability Density Function (PDF) describes the probability that a given value u will occur.

ToString ( string format, IFormatProvider formatProvider ) : string

Returns a System.String that represents this instance.

UMinimum ( double ranks, int n1, int n2 ) : double

Gets the Mann-Whitney's U statistic for the smaller sample.

USample1 ( double rank1, int n2 ) : double

Gets the Mann-Whitney's U statistic for the first sample.

USample2 ( double rank2, int n1 ) : double

Gets the Mann-Whitney's U statistic for the second sample.
